Wet tissue package

ABSTRACT

A wet tissue ejection hole formation member which includes a wet tissue ejection hole and an oppositely disposed flange portion is disposed at an inner side around an opening of a bag body where a wet tissue is accommodated with the flange portion being glued. A flat cross section area of a concave space between the bag body opening and the wet tissue ejection hole formation member is larger than an opening space of the bag body opening. A sheet-shaped cover body is glued to the bag body at a position where the flange portion of the wet tissue ejection hole formation member overlaps at least in part with each of a portion around an edge of a hinge portion for opening and closing the cover body and a portion around an edge of an opening side.

TECHNICAL FIELD

The present invention relates to a wet tissue package that stores and packages wet tissues in a bag body.

BACKGROUND ART

Wet tissues are widely used for wiping one's hands or the buttocks of infants, sick persons, or old persons. A wet tissue is base fabric such as nonwoven fabric impregnated with a chemical such as a cleaning liquid, an antiseptic liquid or the like and is normally stored in a sealed storage container to be able to maintain a state in which the base fabric is wet with a chemical or the like. A bottle-type storage container in a cylindrical shape has widely been used, but a bottle-type wet tissue package stores a wet tissue wound as a roll vertically in an storage container and thus, it is difficult to make the container compact, posing a problem of larger sizes of the storage container and higher manufacturing costs. In recent years, therefore, instead of the bottle-type wet tissue package, a bag-type wet tissue package enabling one to take out one folded wet tissue at a time by storing and packaging folded wet tissues in a bag body is increasingly used.

As a bag-type wet tissue package, a wet tissue package configured such that a wet tissue drawing hole forming member or an outlet member formed a wet tissue drawing hole at the bottom portion is mounted on the inner side around a bag body opening formed from a film having airtightness or the like and a wet tissue inside the packing body is taken out from the bag body opening through the wet tissue drawing hole is widely used (see, Patent Literature 1).

As a wet tissue package of the related art, a package has been widely used which seals an opening of a bag body by a sheet-like cover in an openable and closable manner (see Patent Document 2).

SUMMARY OF INVENTION Technical Problem

Wet tissues stored inside the bag-type wet tissue package in a folded state can be taken out one wet tissue after another by tearing along the perforation or the like. The opening of the bag body is sealed with a cover such as a cover unit member or an airtight film and the method of folding wet tissues and the shape of the drawing hole are devised such that when the cover is unsealed and a wet tissue is pulled to take out the wet tissue, the tip portion of the next wet tissue is protruded from the drawing hole. If a wet tissue with the tip portion thereof protruded from the wet tissue drawing hole is left alone, the wet tissue is dried and it is necessary to seal the opening of the bag body again if there is some time before the wet tissue is used next time and the tip portion of the wet tissue protruding from the drawing hole is stored in a space between the drawing hole and the opening of the bag body. However, a conventional bag-type wet tissue package has only a narrow space formed between the wet tissue drawing hole and the opening of the bag body and thus, even if an attempt is made to seal the opening of the bag body with the cover, it is difficult to reliably seal and store the tip portion of the wet tissue protruding from the drawing hole in the space between the drawing hole and the opening of the bag body. Particularly if the remaining amount of wet tissue in the bag body decreases, the volume of the tip portion of the wet tissue protruding after being pulled out from the drawing hole increases. Thus, it becomes difficult to seal and store the tip portion protruding from the drawing hole reliably in the storage space. In addition, there is a problem of an increased size of the whole packing body if the volume of the storage space is increased by increasing the depth from the opening of the bag body to the bottom portion of the outlet member and also a problem that if an attempt is made to retain the size of the packing body, it is unavoidable to reduce the amount of wet tissue stored in the bag body. Further, a package of which an opening of a bag body is sealed by a sheet-like cover is provided at low cost. However, the periphery of the opening of the bag body is wrinkled when the opening of the bag body is sealed again by the cover, and hence it is difficult to stick the cover to the periphery of the opening in a close contact state. As a result, a problem arises in that the opening of the bag body may not be reliably sealed again.

The present invention is made to solve such problems of the related art, and an object thereof is to provide a bag type wet tissue package that stores a front end of a wet tissue popping out from an drawing hole in a space between the drawing hole and an opening of a bag body and reliably seals the opening of the bag body by a sheet-like cover again.

Solution to Problem

Namely, the gist of the present invention is

(1) A wet tissue package that seals an opening of an air-tight bag body storing a wet tissue by a sheet-like cover in an openable and closable manner, wherein a outlet member formed a wet tissue drawing hole and facing flange portions is attached to the inside of the periphery of the opening of the bag body by sticking the flange portions to the bag body, a space of a concave portion between the opening of the bag body and the outlet member is formed so that its plane cross section is larger than the opening area of the opening of the bag body, and a sheet-like cover is stuck to the bag body so that a periphery of an edge of a portion serving as a hinge portion used for an operation of opening and closing the sheet-like cover and a periphery of an opening side edge are respectively located at positions partially overlapping at least the facing flange portions of the outlet member, thereby sealing the opening of the bag body.

(2) the wet tissue package according to (1) above, wherein at least a portion of the side wall of the outlet member has a shape of communicating through the bag body,

(3) the wet tissue package according to (1) above, wherein the outlet member is mounted in a recessed position on the inner side from an edge of the opening of the bag body,

(4) the wet tissue package according to (2) above, wherein the outlet member is mounted around the opening of an inner surface of the bag body via the flange portion formed by overhanging from the edge of the upper end portion of the outlet member to an outer side,

(5) the wet tissue package according to (1) above, wherein the outlet member is configured by processing and forming the wet tissue drawing hole and the flange portion in a plate body.

Advantageous Effects of Invention

A plane cross section of a concave space of a outlet member is formed larger than an opening area of an opening of a bag body in a wet tissue package in the present embodiment; therefore, the volume of the concave space is large and drying of a wet tissue can be prevented by reliably sealing and storing a tip portion of the wet tissue protruding from an drawing hole in the concave space. Further, there is no need to worry about a problem in which the cover is stuck to the opening in an incomplete contact state due to the wrinkle formed in the periphery of the opening of the bag body when the opening of the bag body is sealed again by the cover. For this reason, since the package may be reliably sealed again, it is possible to prevent the wet tissue from being dried.

DESCRIPTION OF EMBODIMENT

FIG. 1 shows an outside configuration of a wet tissue package 1 of the present invention and reference numeral 2 is a bag body, reference numeral 3 is an opening of the bag body 2, a reference numeral 4 is a cover. FIG. 1A shows a state in which the opening 3 of the bag body 2 is sealed with the cover 4 made of an airtight film or sheet and FIG. 1B shows a state in which the opening 3 is unsealed by opening the cover 4. As shown in FIG. 2, folded wet tissues 5 are stored inside the bag body 2.

The bag body 2 is formed in a bag shape such as a pillow shape as shown, for example, in FIGS. 1A and 1B by sealing ends of the plastic sheet or film having airtightness with a heat seal or the like. The bag body 2 is made of an airtight material and is formed of, as shown, for example, in FIG. 2, a 2-layer layered product of an inner layer 2 a and an outer layer 2 b. A layered product of one or two or more of, for example, polyethylene, polypropylene, polyester, polyamide, vinyl chloride, vinylidene chloride, and cellophane or a complex obtained by further stacking aluminum foil is used as the inner layer 2 a, and polyethylene terephthalate (PET) or the like is used as the outer layer 2 b. In the present embodiment, the bag body 2 is formed of the two layers of the inner layer 2 a and the outer layer 2 b, but is not limited to such an example and may be formed of multiple layers of three layers or more, or one layer. In addition, materials used for the inner layer 2 a and the outer layer 2 b are not limited to the above materials.

The wet tissues 5 are ground fabric such as nonwoven fabric impregnated with a chemical such as a cleaning agent, an antibacterial or the like and are stored in the bag body 2 after being folded. The wet tissues 5 are folded and stored such that the wet tissues can be taken out one by one.

An outlet member formed a wet tissue drawing hole 6 is mounted on the inner side of a periphery of the opening 3 of the bag body 2. The outlet member 6 is made of paper, synthetic resin, metal or the like and is formed from, for example, a punched molded body of paper, a synthetic resin sheet or film, a thermal molded body of a thermoplastic resin sheet or film, an injection molded body of thermoplastic resin or the like. The outlet member 6 is formed in a box shape having a concave space 7 as shown, for example, in FIG. 3 and a flange portion 6 a formed by overhanging to the inner side of the edge of the upper end portion is fixed to and mounted on the periphery of the opening 3 of the bag body 2. A wet tissue drawing hole through which the wet tissue 5 in the bag body 2 is taken out is provided at the bottom portion of the outlet member 6. The outlet member 6 is fixed by sticking the flange portion 6 a to the bag body 2 by an emulsion adhesive, a hot-melt adhesive, a heat-seal, or the like, but the present invention is not limited to the case where the entire surface of the flange portion 6 a is stuck to the bag body 2. For example, a part of the surface of the flange portion may be stuck to the bag body at some spots. The concave space 7 of the outlet member 6 is a space in which a tip portion 5 a of the wet tissue 5 to be taken out next is stored and the wet tissue package 1 in the present invention has the outlet member 6 formed such that the plane cross section of the concave space 7 is larger than the opening area of the opening 3 of the bag body 2 to allow the tip portion 5 a of the wet tissue protruding from the wet tissue drawing hole 8 to be sealed and stored reliably in the concave space 7. In the outlet member 6 illustrated in FIG. 3, the flange portion 6 a provided to mount the outlet member 6 to the peripheral edge of the opening 3 of the bag body 2 is formed on four sides of the outlet member 6 so as to protrude inward from the peripheral edge of the upper end of the outlet member 6, and the plane cross section of the concave space 7 is larger than the opening area of the opening 3.

The wet tissue drawing hole 8 is configured such that the wet tissue 5 stored in the packing body 2 is taken out one by one and, as shown, for example, in FIG. 4, a picking portion 8 a and a pulling portion 8 b whose opening area is smaller than that of the picking portion 8 a are linked via a tapering portion 9 of the picking portion 8 a. The pulling portion 8 b is provided with a protrusion 10 to apply a load to the wet tissue to be pulled out and a slit 11 to allow the wet tissue to be taken out easily one wet tissue after another by providing an elastic force to the load applied to the wet tissue by the protrusion 10. The wet tissue drawing hole 8 is not limited to the shape shown in FIG. 4, and any shape allowing the wet tissue 5 to be taken out one by one may be adopted and various shapes shown in, for example, FIGS. 5A to 5H may be adopted.

When the user uses the wet tissue package 1 for the first time, the tip portion 5 a of the wet tissue 5 does not protrude into the concave portion 7 after the cover 4 being unsealed. Thus, as shown in FIG. 6, the user picks and pulls up the wet tissue 5 in the packing body 1 from the picking portion 8 a. At this point, with a folding line 12 of the folded wet tissue 5 being stored inside the bag body 2 so as to be in a direction perpendicular to the direction connecting the picking portion 8 a and the pulling portion 8 b of the drawing hole 8 (direction along an arrow in FIG. 4), the wet tissue 5 moves in the direction of an arrow A in FIG. 6 and moves from the picking portion 8 a to the pulling portion 8 b via the tapering portion 9 while being pulled up. At this point, a load is applied to the wet tissue by the tapering portion 9 and the protrusion 10 and if the wet tissue is further pulled up, a first wet tissue and a second wet tissue are separated while the tip portion 5 a of the second wet tissue protrudes from the pulling portion 8 b. Then, when the second or subsequent wet tissue is pulled out, the tip portion 5 a of the wet tissue protrudes from the pulling portion 8 b and so the protruding tip portion 5 a can be picked and pulled up to take out the second wet tissue and because a load is applied to the wet tissue 5 by the protrusion 10 of the pulling portion 8 b, the second and third wet tissues are separated while the tip portion 5 a of the third wet tissue protrudes from the pulling portion 5 b.

When the wet tissue 5 is not further taken out, drying of the remaining wet tissue can be prevented by storing the tip portion 5 a inside the concave space 7 and sealing the opening 3 of the bag body 2 with the cover 4. The packing body 1 in the present invention is formed such that the plane cross section of the concave space 7 is larger than the opening area of the opening 3 and the volume of the concave space 7 and thus, when the remaining amount of the wet tissue 5 in the bag body 2 is small or even when the amount of protrusion of the tip portion 5 a of the next wet tissue protruding from the wet tissue drawing hole 8 because the pull-up force when a wet tissue is pulled out is too strong, drying can be prevented by reliably storing and sealing the protruding tip portion 5 a inside the concave space 7.

In the opening 3 of the bag body 2 of the wet tissue package 1 of the present invention, the opening 3 is sealed by sticking the sheet-like cover 4 to the periphery of the opening 3 through an adhesive layer so that the opening 3 may be repeatedly sealed and opened. In the sheet-like cover 4, the sticking position in the periphery of the edge of the portion serving as the hinge portion 4 a used for the operation of opening and closing the cover 4 becomes a position that partially overlaps at least the attachment position of the flange portion 6 a of the outlet member 6 with respect to the bag body 2. Furthermore, the cover 4 is stuck to the bag body 2 so that the peripheral position of the opening side edge 4 b of the cover becomes a position partially overlapping at least the position of the flange portion 6 a facing the flange portion 6 a (the flange portion 6 a overlapping the sticking position of the periphery of the edge of the portion serving as the hinge portion 4 a of the cover 4) in the outlet member 6. The sheet-like cover 4 seals the opening 3 while being stuck to the bag body 2 so that the attachment position of the periphery of the edge of the portion serving as the hinge portion 4 a used for the opening and closing operation and the position of the periphery of the opening side edge 4 b of the cover 4 are respectively located at positions partially overlapping at least the positions where the facing flange portions 6 a of the outlet member are stuck to the bag body. Accordingly, since the peripheral edge of the bag body the opening 3 is not wrinkled when the opening 3 of the bag body is sealed again by the cover 4 after the opening operation and the cover 4 may be stuck to the peripheral edge of the opening 3 in a close contact state, the package may be reliably sealed again. As the adhesive for sticking the cover 4 in an openable and closable manner, for example, an adhesive mainly containing an acrylic fabric size, polyvinyl chloride composition containing plasticity, craft copolymer in which an ethylene-vinyl acetate copolymer is craft-polymerized with an vinyl chloride monomer or the like can be cited, but is not limited to the above examples if the adhesive is capable of repeatedly paste and separate the cover 4. The cover 4 is formed by a sheet or a film that is single, or multiply laminated layers with two or more such sheets of a synthetic resin having air-tightness like the bag body 2. When the cover is formed in a size in which the sticking position of the periphery of the edge of the portion serving as the hinge portion 4 a and the position in the periphery of the opening side edge 4 b partially overlap at least the facing flange portions 6 a and 6 a of the outlet member 6, the length of the cover may be slightly larger or smaller than the length of the outlet member 6 (the length from the edge of the flange portion 6 a to the edges of the facing flange portions 6 a). However, it is desirable that the length of the cover is substantially equal to the length of the outlet member 6 as illustrated in the drawings.

In the wet tissue package 1 of the present invention, the outlet member 6 is not limited to the shape shown in FIG. 3 and any shape capable of making the plane cross section of the concave space 7 larger than the opening area of the opening 3 of the bag body may be adopted and, as shown in FIG. 7, a shape in which a communicating portion 13 communicating through the bag body 2 in at least a portion of a side wall 6 b may be adopted. If the communicating portion 13 is provided, the space inside the bag body 2 can also be used as the concave space 7 to accommodate the tip portion 5 a of the wet tissue 5 and so the size of the outlet member 6 can be made smaller. In the example shown in FIG. 7, while the communicating portion 13 is provided only on the opposing two sides of the side walls 6 b of four sides, the communicating portion 13 may also be provided in the side walls 6 b of all the four sides. When the communicating portion 13 is provided in the side wall 6 b, the flange portion 6 a is not limited to one formed by overhanging from the edge of the upper end portion of the outlet member 6 to the inner side and may be formed by overhanging to the outer side. Even when the aforementioned flange portion 6 a is mounted along the edge of the opening 3 of the bag body 2 or mounted on the bag body 2, as in a different mode (FIG. 9) described later, in a position on the inner side from the edge of the opening 3, the plane cross section of the concave space 7 can be formed larger than the opening area of the opening 3.

The outlet member is not limited to this embodiment that has the flange portion 6 a provided at each of four sides thereof, and the flange portion 6 a may be provided only in a pair of facing edges as illustrated in FIGS. 8A to 8C. The outlet member 6 illustrated in FIGS. 8A to 8C is formed so that at least a part of the side wall communicates through the bag body 2. While the outlet member 6 in the shapes shown in FIGS. 3 and 7 is normally manufactured by injection molding, the outlet member 6 as shown in FIGS. 8A, 8B, or 8C can be manufactured by a simple method such as stamping the drawing hole 8 in a plate body of synthetic resin and then pressing the plate body into a right-angle shape or a curved shape, or stamping the drawing hole 8 in a long molded body formed by extrusion and cutting the molded body.

FIG. 9 shows a different mode of the wet tissue package 1 of the present invention. The wet tissue package 1 has as the outlet member 6 a shape in which the flange portion 6 a is formed by overhanging from the edge of the upper end portion of the outlet member 6 to the outer side, but is formed such that the plane cross section of the concave space 7 is larger than the opening area of the opening 3 of the bag body 2 by mounting the flange portion 6 a on the bag body 2 in a recessed position on the inner side from the edge of the opening 3 of the bag body 2; therefore, a sufficient volume of the concave space 7 can be secured and the tip portion 5 a of the wet tissue 5 protruding from the wet tissue drawing hole 8 to the concave space 7 can reliably be sealed and stored inside the concave space 7.

As a method of folding the wet tissue 5 packaged in the wet tissue package 1 in the present invention, for example, as shown in FIG. 10A, the long folded wet tissue 5 provided with a tear-off portion 14 such as perforation at predetermined intervals, as shown in FIG. 10B, a plurality of wet tissues 51 folded in a Z shape called Z folding in which ends thereof are made to mutually overlap, as shown in FIG. 10C, the plurality of wet tissues 51 folded in a Z shape and a plurality of wet tissues 52 folded in a W shape called WZ folding in which ends thereof are alternately made to mutually overlap and the like can be cited, but the method of folding is not limited to the above examples and various method of folding like folding combining vertical folding and horizontal folding can be adopted.
